University of Arizona Offers Screwworm Testing Kits to Livestock Producers Amid Outbreak
The University of Arizona (U of A) is providing New World screwworm testing kits to livestock producers at nearly all U of A Cooperative Extension locations to aid in detection efforts. This initiative comes as four cases of New World screwworm have been confirmed in Arizona, prompting animal health officials to monitor for the parasite and take steps to prevent its spread. The New World screwworm is a parasitic fly whose larvae feed on the living tissue of warm-blooded animals, entering through open wounds and causing serious damage if left untreated. Flavie Audion, a rangeland management specialist at the University of Arizona, explained that the screwworm feeds on live flesh and can impact a wide range of animals, including cattle, sheep, goats, horses, dogs, cats, wildlife, and potentially humans. When a case is confirmed, officials establish a mandatory 20-kilometer (12.4-mile) Infested Zone around the detection, within which live animals cannot leave without authorization from the state veterinarian.
